Notice of Posting of Non-Operating Income (Foreign Exchange Gains)

JGC Holdings Corporation (the "Company") hereby announces that in the first quarter of the fiscal year 2022 ending March 2023, the Company posted non-operating income (foreign exchange gains).

1．Breakdown of non-operating income (foreign exchange gains)

Due to recent fluctuations in the foreign exchange market, we posted ¥5.99 billion in foreign exchange gains under non-operating income for the first quarter of the fiscal year ending on March 31, 2023 (April 1 to June 30, 2022).

This is primarily due to valuation gains resulting from the valuation of foreign currency- denominated assets and liabilities held by the Company and its consolidated subsidiaries as of the end of the first quarter at the exchange rates as of the end of the first quarter, and thus could change depending on conditions in foreign exchange markets going forward.

2. Impact on financial results

Please refer to the "Summary-Consolidated First Quarter Financial Statements" released today, for details on the impact that the aforementioned posting of non-operating income (foreign exchange gains) has on financial results.
